CLUTCH-PEDAL LOCK.

Application filed July 30, 1920. Serial No. 400,290.

To all whom it may concern:

Be it known that I, HURVY N. FULLER, a citizen of the United States, and a resident of Oto, in the county of Woodbury and State of Iowa, have invented certain new and useful Improvements in- Clutch-Pedal Locks, of which the following is a specification.

My present invention has, for its primary object, the production of an improved lock mechanism for the clutch-controlling lever of such motor vehicles as the Ford, which employsthe planetary type of transmission gearing. A further object of the invention is the production of a clutch-pedal lock, inexpensive in construction, thoroughly efiicient and dependable in operation, and readily applied to a Ford car.

The above and other objects and advantages I successfully attain in the embodiment hereinafter described, defined in the appended claims and illustrated inthe accompanying drawings which form a part of this application, and of which:

Fig. 1 is a fragmentary, transverse section of the foot-boards of a motor vehicle, with the device of my invention applied thereto and in locked position. v

Fig. 2 is a similar view with the device unlocked and retracted, and Figure 3 is a rear elevation of the same.

Although I have illustrated and hereinafter described but .one embodiment suitable for practicing the invention, I would not he understood as being limited to such specific structure, for many alterations and modifications may be made in the details of construction and arrangement of parts herein disclosed without departing from the spirit and scope of the invention as defined in the appended claims.

In the illustrations 4 represents the usual foot-boards of a Ford motor-vehicle, having a slot, 5, through which the familiar clutchpedal lever, 6. is free to oscillate forwardly and rearwardly.

On the lever, 6, I pivot, as at 7, a bar, 8, which extends rearwardly from the pedal, 6, and is provided on its lower rear end portion with ratchet teeth, 9. The said bar is free to reciprocate through a slot. 10, in a guide-plate, 11, suitably mounted on the foot-board, 4, and so positioned that when the pedal, 6, is forced forwardly the ratchet teeth, 9, will engage the portion, 12, of the plate, 11, at the lower end of the slot, 10, to prevent retraction of the pedal, 6.

13 is a plate mounted to slide vertically.

on the front of the plate, 11, and is provided with a slot, 14, through which the bar, 8, is free to reciprocate. The said plate, 13, is held, normally, yieldably downwardly by means of a retracting spring, 15, secured to the said plate and the foot-board, 4, by means of which construction the plate, 13,

holds the bar, 8, againstthe portion, 12, or

operative positions I mount, in the rear of the plate, 11, a horizontally-rotating cam, 19, on which the bar, 8, freely slides. The

said cam is provided on one side with an enlarged part, 20, so constructed and related to the lever,8, that when the cam is so turned that the bar, 8, rides the part, 20, the bar will freely reciprocate through the slot, 10, without engagement with the detent, 12. The cam may be provided with a lateral projection, 21, with which the operator may engage his foot to turn the cam in either direction. 7

Having thus described my invention, what I-claim as new and desire to secure by Letters Patent of the United States is: I

1. The combination with a motor-vehicle, including a forwardly and rearwardly movable clutch-lever and a fixed vehicle part-in the rear thereof, of a bar pivoted on the lever, extended rearwardly therefrom and provided with teeth, a detent on said part for engagement by the teeth and a foot-lever extending transversely of and positioned below the bar, one end thereof being engageable with the under side of the bar to lift it from the teeth from the detent.

2. The combination with a motor-vehicle including a forwardly and reerwardly movable clutch-lever and a fixed vehicle part in the rear thereof, of a' bar pivoted on the 5 lever, extended reerwardly therefrom and provided with teeth, a detent on said part for engagement by the teeth, means for lifting the bar to disengage the teeth, and a rotating cam on said part to hold the bar in operative and inoperative positions. 10

In testimony whereof, I have hereunto set my hand this 12th day of July, 1920.

HURVY N. FULLER.
